Bob Woodruff was interviewing Bruce Springsteen backstage at the Stand Up for Heroes benefit Wednesday, but made the mistake of taping it too near a bathroom. A spy reports, “Every time Springsteen started speaking, the toilet began flushing. They restarted the interview, but the loud flushing continued.” Turned out Stephen Colbert was sabotaging the audio on purpose — to much amusement. The event raised more than $1.3 million for theBob WoodruffFoundation. (More on the night from Cindy Adams here.)
